The Pleasures of Imagination - The Second Book - The Argument
Introduction to this more difficult part of the subject. Of truth and its three classes, matter of fact, experimental or scientifical truth, (contradistinguished from opinion) and universal truth: which last is either metaphysical or geometrical, either purely intellectual or perfectly abstracted. On the power of discerning truth depends that of acting with the view of an end; a circumstance essential to virtue. Of virtue, considered in the divine mind as a perpetual and universal beneficence. Of human virtue, considered as a system of particular sentiments and actions, suitable to the design of providence and the condition of man; to whom it constitutes the chief good and the first beauty. Of vice and its origin. Of ridicule: its general nature and final cause. Of the passions; particularly of those which relate to evil natural or moral, and which are generally accounted painful, though not always unattended with pleasure.
